T 0, all 1071 0m it may concern Be it known thatIyAnA H. PRENZEL, acitizen of theUnited States, residing at Halifax, in the countyofDauphin'and State haveinvented certain Improvements in Upper-FormingMachines, of which the following description, in connection withtheaccompanying drawings, is a specification, like reference characterson the drawings several figures. i w v This invention relates tomachines for preparing uppers of stitch-down shoes for particularlytomachines for preparing the heel end of a stitch. down upper to receivethe sole.

a stitch-down shoe upper hasbeen success]- fu 1y practisedand an objectof the invenforflanging the heel endof a shoe upper which will utilizethe important principles' of operation above set forth.

To this end the invention contemplates."

the provision of meansfor firstformin'g a crease in the heelend of theshoe upper alongthe line aboutwhich it the flange, whereby the upperwill be gaththen to hold the upper in the creasing means while theprojecting portion of the upper from which the flange is to be formedis'. turned out upon said'creasing means. i

i An important feature" of the invention i s the provlsion of simple,efficient and easily interchangeable means for shaping'the heel andmaintaining the shape operation. p 7 a p Another important feature ofthe invention is'the provision of novel means cooperating with thecreasing means'jfor effecting s desired to turn turning line, I and tionis to provide simplefand efiicient means the turning out andthe pressingout of the outturned flange; r v

Other important features of the invention are means for presenting thework, together with novel means for locating the work in the machine;novel means for holding the .j

work in proper the different mechanisms which are to oper: ate insuccession,an'd a novelarrangement of the creasing elements whereby thecreasposition as it ispresented to ing operation may be performedeffectively at the forward end'of the heelportion of the upper, in theregion of the shank.

Still other important features and objects of the invention willbeapparent when the following descriptioaandclaims are consldered 1nconnection with the accompanying drawings in which Figure 11s a sideelevatlon of themachlne elevation; Fig. '3'isfa longitudinal sectionthrough the machine, showing a perspective detail illustratingthe modeof e e embodying the invention; Fig. 2 is a front the parts in yFis- .1.

The illustrated machinefisa'dapted to "be section illusqtheupperi's pressed against the support 2 and maintained in the relationto said support which has been determined for it by the gaging means. bemoved out of-:operat1ve relation to the upper to facilitate thefurther'movement of i the support 2vand the upperinto the creaslngmeans. The upper retaining device 76 is carried upon the forward end ofa rod/78- 10? moved into operative relation to the creasing vmeans by pa spring '84 confined between a collar 86,=pivoted upon the rod78 andthe stud 80, the spring being compressed as the rod 78 slides toward thestuds 42 and 80.- I

The upper having been brought into operative relation to the creasingmeans and the creasing means having. been operated through the lever 52to force the upper into the crease receiving groove 4, it will "beapparent that the margin of the upper'projecting beyond the creasing.plates 14, 16 and 18 will be given a tendency to turn-out by reason ofthe fullness along the flange line and by reason of thefurther fact thatthe upper sideof the crease receiving groove 4 overhangs considerablythe lower side.

In order tocompletethe'turning process and also to press andsmooth theflange out, means has been provided which may be broughtintoengagementwith the flange and i which can be operated to progressivelyturn out and smooth out this flange." 'The illustrated meanscomprises aroller 88 mount; ed to turn about a short shaft supportedby hangers 90depending from a slide 92 arranged to slide in guides 94 in thecrosshead 96. The cross-head 96*has vertical cuplike bearings whichreceive and are guided upon vertical posts 68, 98,100 and 102, each ofthese posts being provided with a collar rigidly confined thereon and aspring between, the cross-head bearing and said collar by which thecross-headis maintained normally in its highest position. The cross-headmay be depressed to bring the roller into operative relation to theupper confined between the work support 2 and the creasing means, byconnections with a treadle 103 comprising a link 104 pivotally"connected at one end tothe cross-head and connected at the other end toan arm 106 upon a rock shaft 108 having a second arm 110 rigidlyconfinedthereon, the arm 110 being connected to said treadle.

The flange turning and pressing out operation is preferably performed bymoving the roller from the shank toward the rear The gaging means cannow" erative relation. to

to, determine a flange line,

end of the upper and in order to efl'ectthis movement of the rollermeans has been provided formoving the slide92 forward and backward uponthe cross-head 96. The illustrated means comprises a lever 112 fulcrumedat 114 between ears upon an inclined support 116 upon the crosshead,this lever being connected by a link 118 to the rear end of the slide92. At its front endisa handle 12-0 arranged tion to be grasped by theoperator.
